It's most likely to be like what Loupgarou said.
Usually, it's due to bad water or bad food.

did you feed them dried bloodworms? I notice some of my fishes do that (as if trying to swim with a float) after eating air-filled dried bloodworms.
why I don't do garden hybrids and aquarium strains: natural species is a history of Nature, while hybrids are just the whims of Man.

Yah Choy, that rings a bell.
I remember my cardinal did that when they gorge themselves with the freeze dried food. But not exactly in a verticle position. They seemed to be trying to swim downwards at a 45° angle when their body seemed to be floating upwards.

I know when I kept goldfish a long time ago, feeding them lots of dry pellets causes some swimming difficulty prob when they gorge and the pellets expand in their stomach?
neon tetra disease (ntd) is quite recognised by necrotised flesh near the tail
is there a patch of blackened or blistered flesh near the tail?
Thanks guys for the responses. From what you guys said, I guess my dad may have overfed those fellas. That's the most possible reason now since I don't see any physical abnormalities which suggest any neon tetra diseases. I will keep on monitoring.
